Depart
The hike starts at the small car park on Rue du Pavillon de Chasse in Mériel (Val d'Oise).
Head towards the northern end of Rue du Pavillon de Chasse. Take the path that continues along it, go through the gate and continue straight ahead until you reach the road (D9).
(1) Cross the road, pass the entrance to the Abbaye du Val and continue along the path running alongside the estate's boundary wall. At the junction with a farm track, turn right and continue to the fork 100 metres further on, where you continue straight ahead along the path running alongside the field. This path climbs, then descends into a hollow at the junction with a forest road.
(2) Turn right towards the Marais de Stors Regional Nature Reserve (signposted).
Follow the Marais de Stors, then climb a hill where you pass under the arch of a ruined bridge and arrive at the top of the hill at a junction with a path that you follow to the right.
(3) About a hundred metres further on, you will come to a signposted path coming from the left and turning in front of you.

(10) Turn right, the path crosses a paved road and, from there, becomes a grassy track crossing a cultivated area. The track turns right after about 100 metres.
Continue straight ahead to the edge of the forest where the path enters the woods. It turns left immediately and follows the edge of the woods to a crossroads in a hollow where it joins a GR® marked path.
Turn right onto the path, following either the yellowPR® markings or the red and white GR® markings. The path winds through the woods. It emerges and ends on a farm track closed by a metal gate near the D9 and a bridge over the N184.

You can see the bell tower of the church in Villiers-Adam in the distance behind the trees. Continue, cross a copse, pass a small stud farm and, at the crossroads, turn right onto the rough road lined with telephone poles.
(12) At the next T-junction, turn right onto the farm track. After about 50 metres, turn left in front of a solitary tree onto the track that leads to Rue de Mériel in Villiers-Adam.
Take this road on the right. It will take you to the exit of Villiers-Adam in front of an old brickworks.
(13) Cross the N184 bridge and, after crossing the slip road, immediately turn right onto the narrow pedestrian passageway that leads to the southern end of Rue du Pavillon de Chasse de Mériel, where you will find the car park.
